Grafana loki backup to azure storage account

  1. Will data reside simultaneously on both Loki and Azure (storage account)
  2. Once copied to cloud storage, will the data be truncated from local Loki volume?
  3. How can data residing on cloud storage be accessed for querying
  4. Backups are incremental. But to retrieve do we need to import all the data or can we imports datewise backups
